Small tomato cultivation management (1)

The image above showcases the unique consumption pattern of small fruit tomatoes, which sets them apart from other tomato varieties. Due to their high sugar content and rich flavor, these small tomatoes are not only delicious but also convenient for direct consumption after washing. Their compact size makes them ideal for modern lifestyles, and as a result, their cultivation area is expanding steadily. Among the popular varieties, "Gold Orange No.1" and "Golden Queen" are hybrid types known for their heat resistance, strong growth, and excellent storage properties. Gold Orange No.1 features orange-yellow fruits, while Golden Queen has golden yellow fruits, both with a single fruit weight of approximately 10–15 grams. They offer a sweet, crisp taste and a high carotene content—equivalent to about 2,500 IU of vitamin A—making them an excellent source of essential nutrients. Another notable variety is Xinya No.8, also known as Jade Red Tomato. This half-determinate type exhibits a flavor similar to cherry tomatoes and is resistant to the tomato yellow leaf curl virus. It also has strong heat tolerance and superior quality, making it a preferred choice for small tomato cultivation. The new product "Jioon" (Jade Red No.8) has a natural fruiting rate of 40–64% in summer, which can be increased to 85–95% with the use of auxin. The fruit is elliptical and weighs around 10 grams. It is resistant to wilt disease and the tomato yellow leaf curl virus, does not crack easily, and grows as a semi-determinate plant. With a height of 150–240 cm, it doesn’t require support structures like trellises or tunnels, making it easy to manage. For optimal growth, planting times vary depending on the season: spring (March–April), summer (May–August), and autumn/winter (October–December). Cultivation methods include open field and rain-shed systems. Open fields are used in autumn and winter, while rain-sheds are preferred in spring and summer to protect against excessive rain. Shelves are commonly used for better sunlight exposure and easier harvesting, ensuring high-quality production. In terms of cultivation techniques, nursery management is critical. Seeds are typically sown in seedling trays, with 70-gauge trays used in summer and 120-gauge trays in autumn and winter. Seedlings are protected from pests using 60-mesh nylon nets to prevent silverleaf whitefly infestation. Proper spacing and pruning are also important. For example, double pruning is suitable for non-stop varieties, while four-pruning is used for Xinya No.8. Water and fertilizer management is equally important. Tomatoes prefer well-drained sandy loam soil and should not be planted consecutively. Organic compost is recommended at 2,000 kg per hectare for long-term crops. Topdressing is applied every three weeks, with attention to boron and calcium levels to avoid deficiencies that can cause fruit cracking or poor development. Rain-proof cultivation is essential during summer to prevent fruit cracking due to heavy rains. Net houses are increasingly used, especially for varieties like Xinya No.8, which thrive under such conditions. These structures also help increase sugar content and improve fruit quality. Fruit-setting agents are used during hot seasons to boost yield. Application timing and concentration must be carefully managed to avoid issues like empty fruit or bud damage. Finally, pest control is crucial, with diseases like bacterial spot and yellow leaf curl virus being common threats. Resistance in certain varieties like Xinya No.8 helps reduce losses, but regular monitoring and preventive measures remain essential for successful cultivation.
